[PATCH] spi: aspeed: Fix window offset of CE1

[Cédric Le Goater]

The offset value of the mapping window in the kernel structure is
calculated using the value of the previous window offset. This doesn't
reflect how the HW is configured and can lead to erroneous setting of
the second flash device (CE1).
